I was going to, but my builder told me that they were kinda too peaky for his motor. But he also said that CPI's are the best pipe for ported motors. But, after seeing the rockets out perform the CPI's, I think Im sold on the rockets. I like the look of the rockets, I think CPI's are kinda plain looking. They are still a great pipe though. Im supposed to have my motor back at the end of this month. Well see what happens.
